B. Proton Events
None
C. Geomagnetic Activity Summary
The geomagnetic field was at quiet to active levels. Coronal hole high speed stream effects subsided near mid-period. The greater than 2 MeV electron flux at geosynchronous orbit exceeded event threshold at 14/1130 UTC and remains at high levels.
